Made of fine-textured, highly elastic, and tough vegan leather, it is not only waterproof and scratch-resistant but also contains the original intention of environmental protection and sustainability. The two-color matching design escapes the previous concept of single-color calmness, making the overall style more flexible and changeable, which can easily adjust the length of the pen sheath according to the size of the pen body. It is very suitable for all Y Studio series of pens and other general pens and let the beloved ones also have a stable and comfortable residence.
